c# - sort two dimension array -

i need sort 2 dimension array in ascending order ,i write code in c# sort array sort each line in array not 2 dimension array , how can sort 2 dimension array

        double[,] test_descriptor = new double[3, 3];          double tempr;          test_descriptor[0,0]=7;         test_descriptor[1, 0] = 7;         test_descriptor[2, 0] = 5;         test_descriptor[0, 1] = 3;         test_descriptor[1, 1] = 0;         test_descriptor[2, 1] = 2;         test_descriptor[0, 2] = 1;         test_descriptor[1, 2] = 9;         test_descriptor[2, 2] = 1;           (int = 0; < test_descriptor.getlength(0); i++) // array sorting         {             (int j = test_descriptor.getlength(1) - 1; j > 0; j--)             {                  (int k = 0; k < j; k++)                 {                     if (test_descriptor[i, k] > test_descriptor[i, k + 1])                     {                         tempr = test_descriptor[i, k];                         test_descriptor[i, k] = test_descriptor[i, k + 1];                         test_descriptor[i, k + 1] = tempr;                     }                 }             }          }          (int y = 0; y < 3; y++)             (int x = 0; x < 3; x++)                 console.writeline("y={0}", test_descriptor[x,y]);       }  

sorting true 2d array difficult, because sorting algorithm must take account 2d structure of array. better off if you

• make plain array of size tmp[m*n],
• copy data tmp
• sort tmp
• copy sorted data original array

here how can it:

double tmp[test_descriptor.getlength(0)*test_descriptor.getlength(1)]; (int = 0; != test_descriptor.getlength(0); i++) {     (int j = 0; j != test_descriptor.getlength(1); j++) {         tmp[i*test_descriptor.getlength(1)+j] = test_descriptor[i, j];     } } array.sort(tmp); (int = 0; != test_descriptor.getlength(0); i++) {     (int j = 0; j != test_descriptor.getlength(1); j++) {         test_descriptor[i, j] = tmp[i*test_descriptor.getlength(1)+j];     } }
